Аннотация

The replacement of a distributed radar object by a simple two-point matrix simulator is considered. In this case, the distributed object is replaced by a model composed of two points. It is shown that this leads to modeling errors, expressed in a change in the mathematical expected value of angular coordinate noise. Relationships have been obtained that allow, firstly, to estimate these errors and, secondly, to set the spacing of model points at which their acceptable level is guaranteed.
